제2도는 보오드 상태 추적장치의 상세 회로도.2 is a detailed circuit diagram of the board state tracking device.

Claims (2)

프로세서가 있는 보오드의 상태 추적장치에 있어서, 어드레스, 데이타 또는 외부제어 신호를 추적하도록 선택신호를 발생하는 어드레스 디코더(2)와, 지정된 어드레스를 저장하는 래치부(10), 읽기 신호가 들어왔을 때 래치의 저장내용을 데이타 라인을 통하여 중앙처리장치에 공급하는 버퍼(11), 상기 래치부(10)에 저장된 어드레스와 어드레스 라인의 현재 어드레스를 비교하는 비교부(13) 및 지정 어드레스를 프로그래머블 어레이 로직에 알려주는 래치부(12)로 이루어진 어드레스 추적회로(A)와, 상기 어드레스 추적회로(A)와 동일 구성의 데이타 추적회로(B) 및 외부제어 신호 추적회로(C)와, 상기 추적회로(A, B, C)의 비교기(13) 및 래치부(12)의 출력 신호에 의하여 버스 에러신호 또는 데이타 인식신호를 발생하여 중앙처리장치에 공급하는 프로그래머블 어레이로직(14)으로 구성된 것을 특징으로 하는 상태 추적장치.A board state tracking device having a processor, comprising: an address decoder 2 for generating a selection signal to track an address, data, or external control signal, a latch unit 10 for storing a specified address, and a read signal The programmable array logic includes a buffer 11 for supplying the stored contents of the latch to the central processing unit through the data line, a comparison unit 13 for comparing the address stored in the latch unit 10 with the current address of the address line, and a designated address. An address tracking circuit (A) consisting of a latch unit (12) which informs the controller, a data tracking circuit (B) and an external control signal tracking circuit (C) having the same configuration as the address tracking circuit (A), and the tracking circuit ( Programmable word that generates a bus error signal or a data recognition signal by the output signals of the comparators 13 and latches 12 of A, B, and C and supplies them to the central processing unit. This straight-state tracking apparatus according to claim consisting of 14. 제1항에 있어서, 상기 프로그래머블 어레이 로직은 비교기 및 래치부의 출력이 동시에 하이이고 어드레스 스트로브가 있는 동안 데이타 인식 입력신호가 입력될 때, 또는 어드레스 스트로브가 있는 동안 외부 에러신호가 입력될 때 중앙처리장치(1)에 에러신호를 송출하여 시스템의 동작을 중단시키고, 비교기 및 래치부의 적어도 한 출력이 로우인 상태에서 데이타 인식 입력신호가 입력되면 데이타 인식신호를 송출하여 시스템 동작을 지속시키는 것을 특징으로 하는 상태 추적장치.The central processing unit of claim 1, wherein the programmable array logic is configured to output when a data recognition input signal is input while the output of the comparator and the latch unit are simultaneously high and the address strobe is present, or when an external error signal is input while the address strobe is present. (1) transmits an error signal to stop the operation of the system, and if a data recognition input signal is input while at least one output of the comparator and the latch unit is low, the data recognition signal is sent to continue the system operation. Status tracker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
